Advertising paid apps?

http://androidforums.com – Hello, Does anyone know of effective ways to advertise paid apps? I've heard that banner ads and pay per click don't tend to break even, let alone profit. I'm interested by pay per install but both Appbrain and Tapjoy only offer PPI for free apps (probably because conversion on paid apps is so poor). As far as I know the only people who offer PPI for paid apps are Flurry, but according to this blog post they will stop showing your ad if it converts badly. The minimum payment for a new campaign is $250, and that money will just sit there doing nothing if the ad is not being shown. Ha (General)
